<p>A device (10) and process for sampling tissue and fluid from bodily cavities comprises an aspirating curette (11) with a notch (27) at its distal end (23). The curette (11) is slidably mounted in and encased by a protective sleeve (17) that has a plug (20) at its outer end. The sleeve (17) is shorter than the curette (11) and a removable stop member (19) is provided to initially limit the movement of the sleeve (17) toward the base of the curette. When the sleeve (17) and curette (11) have been inserted into the bodily cavity the stop (19) is removed, permitting the curette (11) to be moved outwardly through the sleeve (17), dislodging the plug (20) and exposing the notch (27). Fluids may be drawn into the curette which is then rotated to scrape the cavity wall, and drawn back into the sleeve (17). The apparatus is then removed from the bodily cavity as a unit with the curette (11) and collected specimen protected from contamination and from oxygen.</p> |
